Grok 4.20 Multi-Agent is a specialized variant of xAI's Grok 4.20 built for collaborative, agent-based workflows rather than single-pass inference. According to xAI's documentation, when a request is sent, multiple agents are launched to discuss and collaborate, each specializing in an aspect of the task — searching the web, analyzing data, or synthesizing findings — before producing a final response. The model can also run without built-in tools, with agents relying purely on their collective reasoning.

Compared with the standard Grok 4.20 it derives from, the multi-agent build adds an orchestration layer that coordinates parallel agents and cross-references information across sources, while retaining native web search and tool use. Per the catalog, it carries a 2 million-token context window and accepts both text and image inputs within that combined budget.

The model exposes reasoning traces during processing and streams its intermediate thinking before final output, per xAI's API examples. Within the broader Grok family, it sits alongside later flagship reasoning releases such as Grok 4.3, which targets agentic workflows and instruction following.

No independently verified benchmark scores for this multi-agent variant were available from primary or top-evaluator sources at the time of writing, so capability claims here are limited to documented features. It is offered through xAI's API as an on-demand model.
